Anthropic Announces First Chief Global Affairs Officer
Anthropic disclosed on Tuesday that it has hired Mariano‑Florentino Cuéllar as its first Chief Global Affairs Officer. In this role, Cuéllar will oversee the company’s policy agenda, international engagement, and government relationships on a global scale.
Cuéllar recently concluded his tenure as President of the Carnegie Endowment for International Peace, a global policy research institution with scholars in 20 countries. Prior to that, he served as a Justice of the Supreme Court of California, where he authored opinions on technology, privacy, international agreements, and separation of powers.
His extensive background includes directing Stanford’s Freeman Spogli Institute for International Studies, co‑directing the university’s Center for International Security and Cooperation, and leading the Stanford Cyber Initiative. He has also served on the President’s Intelligence Advisory Board, the U.S. Department of State’s Foreign Affairs Policy Board, and worked across three presidential administrations in the White House and other federal agencies.
Cuéllar was appointed by the National Academy of Sciences to its Committee on Responsible Computing Research. He co‑chaired the bipartisan Task Force on Nuclear Proliferation and American Security and co‑led California’s Frontier AI Working Group.
Academically, he holds the Cameron Schrier Family Professorship at Stanford Law School, where he has been teaching artificial‑intelligence courses for nearly a decade, and he serves as a Senior Fellow at Stanford’s Institute for Human‑Centered Artificial Intelligence.
Since January 2026, Cuéllar had been a Trustee of Anthropic’s Long‑Term Benefit Trust. He stepped down from that position to assume his new role, and the Trust will appoint a successor through its standard selection process.
"Policymakers in the US and around the world are increasingly realizing that we are at a critical inflection point when it comes to how we govern and develop artificial intelligence," Cuéllar said.
Daniela Amodei, speaking on behalf of Anthropic, noted that Cuéllar "has spent his career helping public institutions respond to times of change with thoughtfulness, pragmatism, and deep commitment to the common good."
